To want to know if my mum is hurt/in hospital

My mum has form for downplaying injuries. A previously broken ankle & wrist (at different times) shows that she seems to go into a kind of shock and has to be persuaded to go to a&e to have it treated.

I live 5 minutes away.

Today my aunt that she lives with called me to tell me mum is in hospital. She fell getting out of bed Friday night but waited till yesterday to go see her GP. Who sent her to hospital and she's been admitted with broken ribs and a punctured lung (I think, that's what mum said but she doesn't always understand - she said my father had a stroke when he had a brain tumour)

I just can't believe that she's been in hospital since yesterday and no one told me. She's been talking to people but no one thought I needed to know.
